Tauberian theorems for (N, p, q, w) summable triple sequences of fuzzy numbers

In this paper, we introduce the notion of weighted mean method (N̄, p, q, w) of triple sequences of fuzzy numbers and and show necessary and sufficient Tauberian conditions under which convergence in Pringsheim's sense of a triple sequence of fuzzy numbers follows from its $ (\bar{N},p,q,w) $ summability. These conditions are weaker than the weighted analogues of Landau's conditions and Schmidt's slow oscillation condition in some senses for three-dimensional case.
